Question

27. Find the volume of a cylinder with height 14 cm and radius 9 cm.

Answer 1

= 3564cm³

Explanation:

Volume of a cylinder

=

`= \pi \: r2 \: h`

therefore

`\pi = (22)/(7)`

from the question

height = 14

radius = 9

volume of the cylinder

`= (22)/(7) * {9}^(2) * 14 \\ = \frac {22}{7} * 81 * 14 \\ = 22 * 81 * 2 \\ = 22 * 162 \\ = 3564 cm3`

therefore volume = 3564cm³
